INV

STERLING C BY K M I United SELF-CONTAINED MOBILE POWER DRIVEN CONVEYER SYSTEM Application July 21, 1951, Serial No. 237,887 13 Claims. (Cl. 19892) This invention relates to a conveyer system which includes a receiving conveyer unit, one or more intermediate conveyer units, and a discharge conveyer unit, all pivotally connected together in tandem relation, one feeding the other.

An object of the invention is to provide improved apparatus of the above mentioned character which is adapted particularly to be connected to and/ or receive material from a mining machine, such as a continuous mining ma chine, and to convey the material, such as coal, without interruption, to a receiving belt conveyer, or the like, the arrangement being such that the continuous mining machine may travel an appreciable distance and be followed by the intermediate conveyer system while discharging at various positions along the length of the receiving conveyer.

In another aspect of the invention it relates to a mining machine, or the like, such as a continuous mining machine, or possibly even a loading machine for mining and/or loading material, such as coal, or the like, the intermediate conveying system being constructed to be attached to or follow closely behind the mining machine which is relatively free to move both longitudinally and laterally, the discharge end of the intermediate conveyer system discharging along at varied positions into a receiving conveyer, or the like.

Still another object of the invention is to provide an improved intermediate transportation or conveyer system for operation between a mining machine, such as a continuous mining machine, or a loading machine, and to deliver the material to any desired receptacle, in which the receiving unit of the intermediate conveyer system and the discharge unit thereof may or may not be power driven but which have steerable wheels, and in which there are steerable wheels on the intermediate unit or units, all such steerable wheels being interconnected and operable in one aspect of the invention from the receiving unit, and in another aspect from the discharge unit, and in still another aspect from both units.

Still a further object of the invention is to provide an intermediate transportation or conveyer system, as above set forth, in which one pair of wheels of the intermediate unit or units are power driven and thus may drive the complete transportation system independent of any mining machine with which it is intended to work.

Still another object of the invention is to provide a transportation or conveyer system including receiving and discharge units and one or more intermediate units, in which power driven traction means is provided on one or more of the intermediate units which are controlled by a hitch on the receiving unit, the hitch being adapted to be connected to a mining machine of the type above mentioned.

Still another object of the invention is to provide a receiving unit of an intermediate transportation system of the general type above mentioned, in which there is a flexible cable hitch extending to the succeeding intermediate unit for controlling the steerable wheels thereof.

Still another object of the invention is to provide an 7 intermediate unit for a conveyer system of the general type above mentioned, in which there are two pairs of interconnected steerable wheels at opposite ends thereof, with hitches connecting each pair of steerable wheels with the preceding and succeeding units of the conveyer system.

Still another object of the invention is to provide a discharge unit for a conveyer system of the above mentioned type, in which there is a discharge boom which is pivotally mounted for swinging movement about an upright axis, and in which there is an independent belt conveyer for the boom, and another belt conveyer for the main body of the unit, and in which the Wheels adjacent the discharge boom can be so adjusted as to raise and lower that end of the unit, thereby raising and lowering the discharge boom.

Other objects of the invention will appear hereinafter, the novel features and combinations being set forth in the appended claims.

In the accompanying drawings:

Fig. 1 is an enlarged plan view, looking downwardly, showing the receiving end of the receiving unit of the conveyer system, with the conveyer belt removed and showing also the hitch between said receiving unit and the associated mining machine, such as the continuous mining machine or conveyer;

Fig. 2 constitutes an extension of Fig. 1, and shows particularly the discharge end of the receiving unit;

Figs. 3 and 4, placed end to end, constitute a plan view, looking upwardly, or from below the receiving unit of Figs. 1 and 2;

Figs. 5 and 6, placed end to end, constitute a plan view, looking downwardly, of an intermediate unit of the conveyer system;

Figs. 7 and 9, placed end to end, constitute a plan view, looking upwardly, or from below the intermediate unit of Figs. 5 and 6;

Fig. 8 is a sectional view taken on the line 88 of Fig. 7, looking in the direction of the arrows;

Figs. 10 and 11, placed end to end, constitute a plan view, looking downwardly, of the discharge unit of the conveyer system;

Figs. 12 and 13, placed end to end, constitute a plan view, looking upwardly, or from below the discharge unit of Figs. 10 and 11;

Fig. 14 is an elevational view showing the receiving end of the receiving unit of Figs. 1, 2, 3 and 4, attached to the discharge end of a mining machine, such as a continuous mining machine or loader, or the like, with which the intermediate transportation system is adapted to 0perate;

Figs. 15 and 16, placed end to end, constitute a side elevational view of said receiving unit, with parts shown in section;

Figs. 17 and 18, placed end to end, constitute a side elevational view of the other side of the receiving unit, as compared with Figs. 15 and 16;

Figs. 19 and 20, placed end to end, constitute a side elevational view of the discharge unit shown in Figs. 10, ll, 12 and 13;

Fig. 21 is a sectional view, with parts omitted, taken on the line 2121 of Fig. 20;

Figs. 22 and 23, placed end to end, constitute a side elevational view of the intermediate section shown in Figs. 5 to 9, inclusive;

Fig. 24 is a sectional elevational view showing the interconnection between an intermediate unit and the discharge unit and it also may represent the interconnection between two intermediate units;
